Title: Improved process of treating waste liquors containing cyanogen compounds
IPC: C02F9/00
Filed: 1925-09-18
Abstract: 250,824. Denis, J. Sept. 18, 1925. Treating-materials; plant.-Waste waters containing cyanogen compounds such as waters from gas manufacture, coke ovens, blast furnaces and certain sugar refineries are treated to render them harmless by adding an alkali or alkaline earth hydrate and ferrous sulphate while passing in carbon dioxide to precipitate iron ferrocyanide which is allowed to settle and adding to the remaining liquor barium hydrate or other reagent capable of forming a carbonate precipitate to carry down any remaining iron ferrocyanide. When the liquor contains phenols and hydrocarbons, these are separated by drawing off the oily layer from the top before or after the addition of one or both of the reagents for precipitating the ferrocyanide in the first phase of the process. The waste liquor is raised from a tank 1 by a pump 2 and pipes 3 to treatment vessels A1, A2 which are worked alternately. Ferrous sulphate solution and milk of lime are prepared in vessels 4, 5 and are supplied to the vessels A1, A2. Carbon dioxide is supplied from a pipe 16. The oily upper layer is drawn off by a pipe 12 into a closed chamber 10 and the settled ferrocyanide sludge is led through a valve 17 to a tank 18 and thence to a filter 19, the filtrate passing through a pipe 20 to a decanting vessel B. The liquor in the vessel A1 after separation of the sludge is then discharged through a valve 24 to the vessel B. Barium hydrate solution from a tank 21 is led to the vessel B, the clarified liquor overflowing at 25 through a pipe 26 while the precipitate as drawn off by a pipe 28, to a pit 29. Hot air or other gas is delivered through a pipe 13 to the vessel 10 and escapes as carburetted air by a pipe 14 from which it may be led to a furnace and burnt. Any sediment in the tanks 4, 5 is discharged into the decanting vessel B. The whole apparatus, except the vessels A1, A2, may be worked continuously.

Title: Improvements in or relating to starting and stopping mechanism for sewing machines orfor fastener-inserting machines for use in the manufacture of boots or shoes
IPC: D05B69/14
Filed: 1926-09-23
Abstract: 258,883. United Shoe Machinery Corporation, (Assignees of Topham, L. E.). Sept.24, 1925, [Convention date]. Switches, quick-action. - Relates to snapaction switches 34, 35 for starting and stopping an electric motor 23 described in application to a shoe-sewing machine. The switch 34 changes the motor connections from forward to reverse and has a spring snap-action through three positions in cyclical order, viz.:-Off, forward, reverse, and again to off after half a revolution. Depression of the treadle 69 actuates the switch from off to forward position; release of the treadle allows one of a pair of pawls to come into the path of a ratchet wheel driven by the motor which thereupon actuates the switch from forward to reverse position at an instant definitely timed with reference to the machine's motion; stoppage of the motor shaft and commencement of reverse movement acts through a friction coupling to bring the switch again to off position. The snap-action of the switch 34 is due to a spiral transmission spring which is compressed by the motor shaft and released in steps by a set of rocking detents. For the first step the release is effected by a cam actuated by the treadle mechanism; for the two subsequent movements the release is effected by the motor shaft mechanism. The switch 35 acts to change the motor connections from low speed to high speed by a snap-action from the treadle when this is depressed in starting the motor, and conversely to change connection back to low speed when the treadle is released, the mechanism being arranged so that this change takes place before the reversal of the switch 34. An additional switch may be provided for actuation by the operator's knee in order to vary the motor speed during running. Means may be added whereby a desired operation of the machine, such as raising the presser foot, may occur as the motor stops.

Title: Improvements in or relating to electro-magnetic switches
Inventor: GRAYSON HARRY
IPC: H01F29/14
Filed: 1952-09-26
Abstract: 773,683. Transformers. STANDARD TELEPHONES & CABLES, Ltd. Sept. 26, 1952, No. 34173/52. Class 38 (2). [Also in Group XXXIX] A static alternating current switch comprises a three-legged core with primary and secondary transformer windings 1, 3, Fig. 1, and means for saturating the core locally at 10 or 11. The windings are linked when the core is saturated at 10. If the core is saturated at 11, the flux follows the central limb 6 and the transformer link is broken. At the points 10, 11 the core includes bridges 13, 14, Fig. 2, controlled by devices described in Specification 738,973, (Group XXXIX]. A bridge 13 comprises four equal arms 15-18 of soft magnetic material which can be saturated by the flux derived from a strong permanent magnet 26 (high coercivity) and a weak permanent magnet 27 (low coercivity). As the bridge is balanced, this flux does not leak into the limb 6. Non-magnetic spacers 30, separate the strong magnet 26 from the yoke member 22, so that the two magnets produce fields of the same strength at points 35, 36. If the magnets 26, 27 are in aiding relation, there is no magnetomotive force and no flux between points 35, 36 and the bridge offers a low reluctance to flux in the limb 6. If, however, the polarity of the magnet 27 is reversed by a pulse in the winding 28, the flux from both magnets flows through and saturates the bridge 13 which then offers a high reluctance to the flux in limb 6. Separate windings 28 may be provided for pulses of opposite sign. The strong permanent magnet 26 has a high remanence and may be of " Alnico " or of one of the materials known by the Registered Trade Marks " Ticonal " and " Alcomax." The bridge arms 15-18 may be of " Permalloy C," " Ferroxcube " or of one of the materials known by the Registered Trade Marks " Mu-Metal," " Perminvar."

Abstract: Textile finishing compositions contain an aqueous dispersion of 1,3-bis-hydroxy-methyl iminazolid-2-one or a water-soluble alkylated or partly alkylated derivative thereof, and an amide of an aliphatic monocarboxylic acid containing at least 12 carbon atoms, or a methylol or ethylol derivative thereof.  Example 1 describes aqueous pasty compositions containing 1, 3-bishydroxymethyl iminazolid-2-one, stearamide, formalin, KOH, petroleum sulphonate and, as non-ionic wetting agents, an ethylene oxide derivative of p-nonyl phenol. Diluted with water and with ammonium sulphate as accelerator these compositions were applied to fabrics and cured.  Example 2 uses compositions of Example 1 to which have been added 1, 3-bis hydroxymethyliminazolid-2-one, sodium dihydrogen phosphate and magnesium chloride.  In Example 3 the pasty dispersion contains 1, 3-bis-methoxy-methyl-iminazolid-2-one, stearamide, formalin, petroleum sulphonate, KOH, and the nonionic wetting agent.  It is diluted with water, and with zinc nitrate an accelerator used for treating fabrics.  Example 4 is similar to Example 3 but to the diluted paste is added 1, 3-bis-hydroxymethyl-iminazolid-2-one. Specification 607,950 is referred to.ALSO:Fabrics are treated to give them improved crease resistance and water repellency with less chlorine retention than fabrics treated with the compositions of Specification 607,950.  The aqueous treating compositions (see Group IV(a)) contain 1, 3-bis-hydroxymethyl-iminazolid-2-one or a water-soluble alkylated or partly alkylated derivative thereof and an aliphatic acid amide containing at least 12 carbon atoms.  In Example 1 cotton fabrics are treated with aqueous compositions containing 1, 3-bis-hydroxymethyl-iminazolid- 2- one, stearamide, formalin, KOH, petroleum sulphonate, an ethylene oxide derivative of nonyl phenol, and ammonium sulphate as curing accelerator.  The resin is cured in the fabric.  In Example 2 the bath contains additional iminazolidone, sodium dihydrogen phosphate and magnesium chloride. In Example 3 the resin pre-cursor used is 1, 3-bis-methoxymethyl iminazolid-2-one, and the accelerator is zinc nitrate.  In Example 4 the aqueous bath of Example 3 contains additionally 1, 3-bis-hydroxymethyl-iminazolid-2-one.

Title: Means for determining distances by reflection of waves
IPC: G01S7/58
Filed: 1935-09-03
Abstract: 464,024. Distance-measuring apparatus. NEUMANN, G. Sept. 3, 1935, No. 24544. [Class 118 (ii)] In a system in which distances are measured by the time taken by a wave to travel from a transmitter to a remote point and back, the wave train comprises impulses of one kind sent out at regular intervals and impulses of other kinds sent out at multiples of this interval. As indicated in Fig. 4 impulses of one frequency are sent out at times Z0, Z1, Z2, &c., impulses of a second frequency are sent out at times HI, &c. and impulses of a third kind are sent at times T1 &c. The transmission of the impulses is controlled by cams 9, 18 and 32 (Fig. 9) respectively which are driven by motor 10 either directly or through gearing as shown, the frequency of impulses being varied by cutting condensers 39 and 64 in or out of the oscillator circuit 4, 5, 6. The impulses are transmitted by transmitter 1 and the reflected impulses are received by receiver 2<1>. Filters 26, 27 and 28 allow impulses of the correct frequencies only to flash lamps 15, 29, 30 which illuminate slots 14, 22 and 33<1> in discs 13, 21 and 33. The discs are driven in synchronism with the cams 9,18 and 32 so that the position of the discs when the signal is received indicates the distance being measured. Suitable scales are provided around the discs so that the distances can be read off by observing the position of the slots when the flashes occur. A distance of 1,260 metres is indicated by the dots in Fig. 6. A cam 42 on shaft 11 opens the receiving circuit to lamp 15 when an impulse is transmitted to prevent the directly received wave being indicated. Instead of the rotating disc and single lamp, the indicators may comprise wipers 43 moving over contacts 44, (see Fig. 11), to which individual lamps 45 are connected, the lamps being provided with suitable delay networks to maintain illumination sufficiently long to allow a reading to be taken. An alarm 49 may also be provided which is sounded only when the distance alters suddenly. When a pulse is received relay 56 is energized and moves lever 55 into contact with disc 54. If the distance is unaltered or has altered by a small amount only the lever contacts with the insulated sections 59 and the alarm is not operated. If a sudden alteration has taken place the lever touches the conducting portion of the disc and the bell rings. The projections 60, 61 are provided to keep the insulated segment 59 in line with the lever 61, a friction drive beingprovided between shafts 50, 53.

Title: Improvements in the manufacture, production and recovery of ammonium chloride and sodium bicarbonate
IPC: C01D7/00
Filed: 1935-09-03
Abstract: In obtaining ammonium chloride and sodium bicarbonate by the reaction of ammonium bicarbonate with sodium chloride with the simultaneous precipitation of the two resulting salts, the reaction is carried out in the presence of substances which cause the ammonium chloride to separate in a coarsely crystalline form, and the resulting mixture of coarsely crystalline ammonium chloride and finely divided sodium bicarbonate is then subjected to a separating treatment.  Suitable substances are urea, biuret and cyanuric acid.  The separation is preferably effected by flotation, if desired with the addition of flotation agents such as oil or salts of fatty acids, the suspension of the finer crystals of sodium bicarbonate being decanted from the larger ammonium chloride crystals.  Alternatively, other separating treatments such as sieving or screening may be employed.
